This book covers the essentials of Kotlin so you can start developing with this amazing programming language. We show nearly everything you need to know in clear and executable code examples.
Kotlin is a powerful language, largely thanks to its expressive syntax, intuitive and null-safe type system, and great tooling support. It’s no wonder Kotlin is the most popular language for Android development and is a popular alternative to Java for backend applications. It is also used for data science and for multiplatform, iOS, desktop, and web application development. In this book, you are going to learn about the most important Kotlin features, which will let you properly start your adventure with Kotlin.
For whom is this book written?
This book is dedicated to developers. I assume that all developers understand what functions, if-statements, or strings are. However, I try to explain (at least briefly) all the topics that might not be clear for all kinds of developers, like classes, enums, or lists. So I assume this book might be read by C, jаvascript, or Matlab developers.
Kotlin is a multiplatform language, but it is mainly used on JVM. Also, most Kotlin developers have experience in Java. This is why I sometimes reference Java and its platform, and I sometimes present JVM-specific elements. Whenever I do this, I state it explicitly. I assume that some readers might be mainly interested in using Kotlin/JS or Kotlin/Native, so everything that is not described as Java-specific should be useful for them.
What will be covered?
In this book, I cover the topics that I find essential for programming in Kotlin, including:
- variables, values, and types,
- conditional statements and loops,
- support for nullability,
- classes, interfaces, and inheritance,
- object expressions and declarations,
- data, sealed, enum, and annotation classes,
- exceptions,
- extension functions,
- collections,
- operator overloading,
- the type system,
- generics.
